This is the first report to investigate the variation of lipids, including glycerolipid, glycerophospholipid, and carotenoid in D.

This paper deals with transfer and accumulation of the radionuclide from phytoplankton Dunaliella to zooplankton Artemia in the graizing food chain of marine organisms.

Perhaps the baton of history will shift to gene technology, from nuclear physics that has lost appropriate international environment after the end of the Cold War. Dunaliella is a unique unicellular species of algae harvested from the dead sea containing rich concentrations of carotenoids mainly betacarotene, antioxidants and essential vitamins.

Students of university of Catania and Palermo were involved into a national event digitalinvasion editions offering their personal contribution: At the transcriptional level, the mRNAs of Rubisco large subunit rbcLand small subunit rbcSattained their highest abundances in the presence of 1. Uptake of tritium oxide and its conversion into organic tritium was studied in four different types of algae with widely varying size and growth characteristics Acetabularia acetabulum, Boergesenia forbesii, two strains of Chlamydomonas and Dunaliella bioculata.

The 9-cis b-carotene occurs only in natural sources and is the most attractive from a commercial point of view. The high amount of lipids produced suggests that D.

The theory manual was developed from several sources including general notes, a programer-notes manual, the user’s notes and of course the material in the open literature. The food chain is the central pathway for nanoparticle transfer from lower to high trophic level organisms. The addition of 8.


If alternation of light and dark is not optimal, algae undergo radiation damage and photosynthetic productivity is greatly reduced. After years of extensive scientific discovery rpopiedades has been learned about the networks that regulate epithelial homeostasis. In the present study, the response propiedqdes D. The algae growth rate in winter conditions in Denmark was slow, but results revealed that large Indeed, an increasing amount of TiO 2 particles settled out zalina time, but the presence of EPS seemed to mitigate this behaviour in the first 6h of exposure where the main effects in D.

Radioecological studies were also performed showing that Acetabularia cells, grown in the presence salija HTO, incorporate a significant amount of 3 H in the total nucleic acid and protein fraction. Dunaliella salina herb uses, benefits, cures, side effects. A notable upregulation of the endogenous hydroxylase level of transformants was observed where the BKT expression was higher in nutrient-limiting conditions.

Bicarbonate-based cultivation of Dunaliella salina for enhancing carbon utilization efficiency. Full Text Available Abstract Background Dunaliella salina Teodoresco, a unicellular, halophilic green alga belonging to the Chlorophyceae, is among the most industrially important microalgae. Many microalgae species are genetically transformable, but the green alga Chlamydomonas reinhardtii is the most widely used host for recombinant protein expression.

The present invention provides conjugates of DNA and cells by linking the DNA to a native functional group on the cell surface. Proposed optimization studies may be helpful to implement the control strategy in scale-up operation. The growth salona algae in this lake is caused by a high concentration of phosphorous that diffuses to the surface of the lake. Effective particle—particle interaction was reduced in the GA-coated NPs.


Metabolic engineering of Dunaliella salina for production of ketocarotenoids. The objective of this paper was the evaluation of the effects of physterols, extracted and purified from D. As a preliminary screening, the expression of the gusA gene and the viability of transformed cells were evaluated and used to calculate a novel parameter called Transformation Efficiency Index TEI. Global warming can be attributed in large part to the burning of carbon-based fossil fuels, as the concentration of atmospheric CO2 is directly related to the burning of fossil fuels.

These results suggest the potential use of the CAH gene promoter to induce the expression of heterologous genes in D. In this work they had cultivated D.

Biotechnology Letters, 24 5— Carotenogenesis of five strains of the algae Dunaliella sp. All the environmental stresses tested produced a substantial increase in both DEVDase activity and protein levels.

The species tested were Nannochloropsis gaditana, Chlorella sorokiniana, and Dunaliella tertiolecta with different cell wall characteristics. Conclusion Present work illustrates Indian Dunaliella strains.

Selection criteria were ease of culture, density of cell suspension, stability of motility and gravitactic orientation. Algal model based multi-objective optimization using elitist non-dominated sorting genetic algorithm with inheritance was carried out for batch cultivation of Dunaliella tertiolecta using NPK-fertilizer.

This study showed that the bicarbonate-based microalgae cultivation is indeed possible, and can even become a truly environment-friendly and workable approach, provided that a CO 2 mineralization technology is concomitantly established.
